Delta Elementary Charter: No single number tells this school's story. Here's the honest picture.

Delta Elementary Charter has a Scope Score of 36 out of 100, placing it in the 31st percentile of California elementary schools and ranked #3,958 statewide. 15.7% of students exceeded the state standard on the 2025 CAASPP assessment, which is 5.6 percentage points below the California average of 21.3%.

Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.

On the 2025 CAASPP Smarter Balanced Assessment, 41.1% of students at Delta Elementary Charter met or exceeded the state standard in ELA and Math combined, and 15.7% exceeded it. The gap between those numbers matters: 25.4% of students are at the proficiency floor, while 15.7% pushed past it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it reveals whether a school's curriculum challenges students beyond minimum proficiency or paces toward it. 272 student-subject combinations were assessed.

Delta Elementary Charter ranks #3,958 among California elementary schools by Scope Score, placing it in the 31st percentile. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), grade-level growth (Grade 3 to grade 5 growth), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.

Based on 2025 CAASPP data, proficiency at Delta Elementary Charter increases by 21.5 percentage points from Grade 3 to grade 5 growth.
